Brown Bear Car Wash will mark its 61st birthday next Thursday (Aug. 23) by offering free "Beary Clean" car washes at its 26 tunnel wash locations from 8 a.m. to 8 p.m.

Last year, more than 30,000 cars and trucks took advantage of the promotion, celebrated on the second Thursday before Labor Day each year. Among the participating locations is the chain's first, at 1800 15th Ave. W. in Interbay. 

“This has become a tradition for us, and it’s our way of saying ‘thank you’ to the communities that have supported us for over 60 years,” said Brown Bear founder and CEO Victor Odermat in a press release. “It’s a fun and busy day as we celebrate with our customers while benefitting the environment.”
